Meranti Awning Window — 1800 x 618mm | 1 Top Opener with Fixed Pane | BM186S
The BM186S is a solid Meranti timber awning window measuring 1800mm wide by 618mm high, featuring a single top-opening casement alongside a fixed pane. Its wide, low-profile format makes it particularly well suited to highlight positions — above doors, below ceilings, or in clerestory applications — where a full-width band of light and ventilation is desired without the height of a standard window.
Available in left-hand or right-hand configuration. Fitted with solid brass handles and easy-clean yellow passivated mild steel hinges throughout.

What Is an Awning Window?
An awning window is hinged at the top and opens outward from the bottom, creating a natural awning effect that allows ventilation even during light rain. Awning windows are a popular choice in South African homes for kitchens, bathrooms, and living areas where airflow is needed without compromising weather protection.
Highlight & Clerestory Applications
The BM186S’s wide, low-profile format (1800mm wide x 618mm high) makes it ideal for highlight window positions — installed above a door or another window to bring additional light into a space without occupying prime wall area. It is also well suited to clerestory installations, where windows are positioned high on a wall to allow daylight deep into a room while maintaining privacy and wall space below.
Choosing Your Configuration (Left or Right Hand)
Stand outside the building facing the window. The hand designation refers to the position of the opening casement relative to the fixed pane. If the opener is on the left, select Left Hand; if on the right, select Right Hand. Contact us if you need guidance before ordering.
About Meranti Timber
Meranti is a dense, durable tropical hardwood widely used in South African window and door joinery. Kiln-dried Meranti offers excellent dimensional stability, good resistance to moisture when correctly sealed, and a fine, consistent grain that accepts paint and stain finishes well. It is a long-established standard in quality South African residential construction.
Hardware Details
This window is fitted with solid brass handles for a premium, corrosion-resistant finish, and easy-clean yellow passivated mild steel hinges for smooth, durable operation. Yellow passivation is a chromate conversion coating applied to mild steel to improve corrosion resistance, making it suitable for interior and sheltered exterior window applications.
Frequently Asked Questions
Is glass included?
No. Timber windows are supplied as frames only, without glass. Glazing must be sourced separately from a local glazier. The frames are rebated and ready to accept standard glass thicknesses.
Can this window be painted?
Yes. Meranti timber takes paint and stain finishes well. Apply a quality wood primer before painting, and use an exterior-grade finish for any windows exposed to weather. Re-coat every 2–3 years depending on exposure.
Is this window suitable for exterior use?
Yes, with correct finishing and maintenance. Meranti timber windows are suitable for exterior applications when properly primed, painted or stained, and maintained. Ensure the cill is correctly weatherproofed and that appropriate flashing is installed.
What is the lead time?
This window is made to order and typically ships within 12–14 business days.
